A simple desktop calendar which shows all the dates in a given year set out
in days and months. Christmas and Easter are highlighted

It is possible to save the calendar either as a text or a graphics file
which can be imported into other programs like word processors. The text
version can be neatly formatted in your word processor by using a ruler with
some right justified tabs. Graphics files are saved with the same layout as
the screen display e.g. four months by three months. You can change the
displayed layout by dragging the bottom corner of the window to make it
narrower or wider.

For the RISC OS version, menu over the main window will open a menu
offering the save options. Graphics files are saved in Draw format

For the Windows version, the standard save window offers graphics formats
of Windows metafile (.wmf), Windows placeable metafile (.wmf), and Windows
enhanced metafile (.emf). The best one to use is .emf, if your software does not
support that try the placeable metafile and failing that the ordinary
metafile. Placeable (and enhanced) metafiles include information about the
size of the graphics contained which improves the chances of other programs
being able to render them correctly.

The program can be given a command line parameter of the year to open at,
otherwise it defaults to the current year.

The adoption of the Gregorian calendar by Britain (and its colonies) is
followed, which makes September 1752 interesting to observe.
